Gather visual elements from at least three of your previous assignments, and create a 'welded image'. Each of the visual elements should be in a separate Command (or multiple Commands). Include comments to explain your choices and the resulting composition.

// for being from four different problems, these images combine 
// very well. i like how the light gray spikes and the black and 
// white triangle are similar (in that they're both triangular), but 
// very different.  more contrast comes from the triangle and the 
// dark curve in the upper left-hand corner.  however, the piece 
// is welded together well. that curve seems to envelope the 
// triangle, and the entire piece.
